Artificial Sub-surface Irrigation:
- When a system of open jointed drains is artificially laid below the soil to supply water to the crops by capillary, it is known as artificial sub-surface irrigation.
- It is a very costly process.
- It requires good-quality irrigation water since water of lousy quality may block the buried perforated pipes.
Additional InformationThe other type of sub-surface irrigation is:
Natural Sub-surface Irrigation:
- Leakage of water from channels, etc., goes underground, and during passage through the sub-soil, it may irrigate crops sown on lower lands by capillarity.
- it is achieved simply by natural process without any extra effort.
